Domain name rules for settings and local data
In Flash Player 6, superdomain matching rules are used by default when accessing local
settings (such as camera or microphone access permissions) or locally persistent data (shared
objects). That is, the settings and data for SWF files hosted at here.xyz.com, there.xyz.com,
and xyz.com are shared and are all stored at xyz.com.
